Rainscreen Cladding involves the installation of a secondary skin of cladding with a ventilated and drained cavity to a new or existing building façade. The system is like a double wall construction that uses the rainscreen outer layer to keep out the rain and an inner layer to provide the structural body of the building preventing excessive air leakage, to provide the structural and wind loading requirements. The outer layer is designed to breathe like a skin while the inner layer reduces energy loss. The structural frame of the building is kept absolutely dry, as water never reaches it or its thermal insulation within. Evaporation and drainage within the rainscreen cavity removes any water that penetrates between panel joints into the cavity. Water droplets are not driven through the panel joints or openings because the rainscreen principle means that wind pressure and temperature acting on the outer face of the panel is equalised within the cavity. Therefore, there is no significant pressure differential to drive the rain through joints. During extreme weather however, a minimal amount of water may penetrate the outer cladding into the rainscreen cavity. This, however, will drain as droplets down the back of the cladding panel and be dissipated at the base of the system or at the heads of any openings through evaporation and drainage from ventilated mesh closure flashings.

OSG are specialists in the design, manufacture, supply and delivery of a wide range of premier Rainscreen Cladding systems offering clients and Main Contractors a complete ‘one stop shop’ cladding solution.

Our team have been involved in numerous prestigious projects throughout the UK including airports, train stations, commercial office buildings, schools, academies, hospitals, leisure facilities, retail environments etc and these projects have varied from the architectural feature cladding of a small entrance area to complete rainscreen facades, facis, soffits, canopies, parapets, cills etc as the business is committed to providing the same level of service and professionalism, irrelevant of the project size, value or location.

Face Fix

Panels can be secretly fixed using either the SikaTack panel adhesive system bonded to either aluminium or timber substrates or a mechanical secret fix system comprising of aluminium brackets anchor fixed into the rear face of the panel which can be mounted onto a horizontal secondary framework rail.

Secret Fix

Panels can be face fixed using either colour coded low profile specialist screws suitable for either aluminium or timber substrates or colour coded rivets to blend in with the chosen panel.

Framework Systems

We can offer a range of secondary framework solutions tailored to meet the need of individual applications / projects. These include Treated Timber, Aluminium Omega and Z, Aluminium Helping Hand or specific product related systems bespoke to individual panel types.

Flashings / Cills / Reveals

As part of our ‘complete cladding solution’ we can manufacture and supply a wide range of Aluminium cladding accessories to compliment the installation including cills, flashings, window / door reveals, perforated head flashings, Top Hat framework, soffits, bulkheads, cappings, casings, pilasters etc .

New Build /Re-furb

Rainscreen Cladding is a perfect solution for both new build and refurbishment schemes as external facades to new builds can be finished within shorter timescales and in a much wider variety of colours / finishes than traditional brickwork, and tired looking existing structures can be easily over clad to improve both aesthetic appearance and thermal efficiency.
